BICYCLE HANDLE-BAR.

SPECIFICATION forming part of Letters Patent No. 589,671, dated September '7, 1897.

7 Application filed October 10, 1894. Serial No. 525,534. (No model.)

To all whom may concern.-

Be it known that I, SAMUEL PALMITER, a citizen of the United States, residing in the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Bicycle Hanc'lle-Bars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide bicycles with an adjustable handle-bar, one that may be readily adjusted to any desired position and held securely in place.

\Vheehnen find the common rigid handle-- bar, which can only be moved up and down in the standard, tiresome and unsatisfactory,

since the rider desires to adjust the handles according to the work he desires to undertake-2 6., low for racing and high for easy road-riding.

My invention entirely obviates the objections named, as the rider can adjust the ham dles instantly to any desired angle and hold them firmly wherever set, changing the curve from a downward to an upward or the reverse, as desired, as will be readily understood by this specification and the accompanying drawings, in which- Figure 1 is a perspective view of a handlebar andhead. Fig. 2 shows the head, screw, and bar in cross-section. Fig. 3 shows head in detail. Fig. a shows section of bar which passes through the head.

In the drawings, B represents the handlebar, which may be made of steel tubing or solid. Curved into desirable form this bar may be made of one or more parts, but should be made larger in the center, where it passes through the head II, to give it strength I and to give room to concave the bar, as shown in Fig. 4.. u. is a coarse screw-thread or worm cut in this concave, as shown, the threads being nearly parallel to the bar.

8 is a screw-bolt which passes through the hole 0 in the head and engages the thread cl, of the handle-bar B, the end of the screw bein g provided with a finer thread than the one engaging the bar and has a set-n ut 22 the head having a slot (2 for a short distance, so that the head will the more readily clamp the bar when tightened by the set-nut and hold more securely.

It is not essential that the screw-bolt have a finer thread at the end to receive the setnut, as a good purpose might be served if the nut were screwed on the large thread, but I prefer to have it as shown.

The bar could beheld by the screw without slotting the head, but it would not be as good. A very good purpose would be served it the threads of the handle-bar only extended part of the circumference of the bar, so the hen dles could be raised or lowered part of the way, but I prefer them as shown.

The same handle-bar may be turned over when it is desirable for ladies or any one wan ting to sit erect on their wheel. It can be turned back and lowered for racing when wanted. It is also more convenient for shipping It will readily be seen that by loosening the set-nut n and turning the milled screw-bolt s that the handle-bar is readily moved any distance desired, and by tightening the nut is as easily secured. The form of this screwhead is not essential, but the one shown is found light and convenient.

The head II may be made in parts and brazed together when desired.

By removing the handle-grip and taking out the screw-bolt the bar is readily removed from the head.

Having full y described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In bicycle handlebars the main barprovided with a worm-gear around said bar, said bar being inserted in a head and held in position by a worm on a bolt engaging the gear of the bar as shown and for the purpose setforth.

2. In bicycle handle-bars the main bar made in one or more parts and provided with a worm-gear around said bar, said bar being inserted in a head and held in position by a worm on a bolt which engages the worm-gear,

said worm-bolt being provided with a set-nut In testimony that I claim the foregoing I as shown, and for the purpose setforth. sign my name in the presence of two witto 3.
